Acoustic emission (AE) serves as a non‐destructive testing (NDT) technique with unique potential for assessing structural integrity and potentially predicting failures in pressure bottles. The authors have effectively demonstrated its applicability in predicting burst pressures of glass fiber reinforced plastic (GFRP) pressure bottles. In their study, five identical GFRP pressure bottles underwent pressurization cycles, and the AE data collected during these cycles was analyzed to develop a straightforward empirical relationship for predicting burst performance. This approach highlights a significant finding: impending failure can be detected with notable accuracy even when pressure levels are at 50%–60% of the maximum expected operating pressure (MEOP), with a reasonable margin of error. Notably, there exists a gap in the existing literature concerning clear methodologies for predicting burst pressures of composite pressure bottles. This methodology, however, can be extended beyond GFRP to predict the burst pressure of pressure bottles made from other material systems in real‐time.Highlights The composite pressure bottle failure is predicted at very low pressure. The prediction is at a range of 50%–75% of MEOP. To predict the burst pressure of GFRP pressure bottle an empirical formula is generated. The empirical formula is generated using Acoustic Emission parameters. Major AE parameters are determined from a set of GFRP pressure bottles.
